PEN.

Application filed. December 2, 1914, Serial No. 875,158.

T 0 all to 710m it may concern Be it known that I, PERCY SWAINE, a subject of the King of England, residing at Sherbrook, in the Province ofQuebec, Dominion of Canada, have invented certain new and usefulImprovements in Pens; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to pens.

The object of the invention is to provide a pen embodying an improvedconstruction whereby same will trace a line of uniform thickness andwill move smoothly over the material being operated upon.

A further object of the invention resides in the provision of a penwhich can be used in connection with either an ordinary pen holder orwith a fountain pen, the essentials of the invention being in no waychanged in adapting the pen for one use or the other.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which Figure 1 is aperspective view of a pen constructed in accordance with the inven tionand adapted for use in connection with an ordinary pen holder;

Fig. 2, a view similar to Fig. 1 showing the pen adapted for use inconnection with a fountain pen, a fragment of the barrel of the latterbeing disclosed;

Fig. 3, a plan view of the pen before the point has been shaped, and

Fig. 1, a longitudinal section of the pen shown in Fig. 1.

Referring to Figs. 1, 3 and 4 the pen is shown constructed from atubular, member A having one end cut away to form a point 10 whichlatter is slitted longitudinally at 11 to form sections 12 and 13. Bycutting away the member A to form the point 10 a tongue 14: is producedwhich is bent inwardly after being suitably shaped so as to almost closeone end of the tubular member A, sufiicient Specification of LettersPatent.

Renewed August 14, 1919. Serial No. 317,634.

space being left between the edge of the tongue and the inner side ofthe point 10 to permit proper feed of the ink to said point. In this waythe tubular member A forms a reservoir 15 in which a relatively largeamount of ink may be stored and gradually fed to the mint 10. The end ofthe tubular member opposite the point 10 is cut away to form atransversely curved shank 16 whereby the pen may be readily associatedwith an ordinary pen holder. In forming the point 10 the sections 12 and13 are left with enlarged portions 17 and 18 respectively, said portionsbeing substantially semi-circular and opposed. The inner ends of theportions 17 and 18 extend contiguous to a limited extent with the outeredges of respective sections 12 and 13. To complete the formation of theouter end of the point 10 the portions 17 and 18 are bent outwardly soas to lie in the same plane with each other and at an angle to thelongitudinal axis of the pen. By providing the flat portions 17 and 18at the outer end of the point 10 it will be obvious that the pen willtrace a line of uniform thickness and operate smoothly over the materialbeing written upon, such a construction being particularly advantageousin the process of lettering.

In adapting the pen for use in connection with fountain pens the memberA is threaded as at 19 just inwardly of the shank 16 so that same may bescrewed into the barrel 20. When the pen is so utilized it will beobvious that the tongue 14: provides the necessary feed.

What is claimed is 2-- A pen including nibs each having at its lower enda segmental extension forming a tip which tips lie in a common plane atan angle to the nibs, the curves of the tips extending from a commonpoint in advance of the lower ends of the nibs to points to the rear ofthe nibs whereby bearings are provided fore, aft and at the sides of thenibs to oppose rising of the forward ends of the tips from a writingsurface under the influence of slightly increased writing pressure.

In testimony whereof I my signature in the presence of two witnesses.
